To all whom it may concern Be it known that we, CHARLES DAVID BON- sam, and FRANK 1V. oner, citizens of the United States, and residents or the city of Parnassus, in the county of lVestmoreland and Staten-l Pennsylvania, have invented a new and useful Improvement in Metal Carlines, of which the following is a specification.

This invention relates to'metal carlines for car roofs and particularly to the form of carline andthe means for, securing the ends of said carline to the side plates of the car. The airline brackets shown in the acconipanying drawing are claimed in our separate application Serial No. 300,822, filed May 31, 1919.

One of the principal objects of the present invention is to produce a'strong and light-weight carline adapted to be used in connection with cars having either metal or wooden side plates and which can be pressed from a rectangular sheet of metal Another object is to secure a distribution 01 the metal throughout the carline suitable for resisting the tendency of the carline to rotate or twist due to the end thrust of the purlins or to the racking and weaving of the car. Another object is to improve the bracket end members and provide t'orsecuring them to the body member of the carline.

The invention consists principally in a c'arline pressed, from a single piece of metal of uniform width, the carline being of sub stantially Z-shaped section at its middle with its web portion gradually diminishing in height from the middle toward each end, the surplus metal gained thereby-being formed into a vertical flange whose depth increases from the middle toward the. ends and which extends downwardly from the top horizontal flangeof the Z to the plane of the lower flange of the 2 where it is then bent outwardly near the end portion of the carline, thus forming an inverted U shape near each end. The invention also consists in improved bracket members which form means for securing the ends of the carl'ine to the side plitt'es. The invention further consists in the arrangements and com- Specification of Letters Patent. Patented Sept, 9, 1919. Application filed January 20, 1919. Serial No. 271,973.

Fig. 13 is a vertical cross-section taken through the car line on the line 13-13 in Fig. 11 lo'oking toward the inner face of the side plate.

In the construction shown in Figs. 1 to 7 of the drawings the carline which is pressed from a piece of metal of uniform width, extends from side to side of the car and comprises a vertical web portion 14: having a lateral flange 15 on its lower edge disposed on one sideof the web and a lateral flange 16 on its upper edge disposed on the opposite side of the web. The oppositely projecting flanges 15 and 16 are of the same width and extend continuously .from end to end of the carline.

The web 14 of the carline gradually di posite side of each end, thus affording surplus which is utilized in forming a vertical je'cting flange 17 carline,

body member of the carline tical flange 25 projecting side of the side plate.

minishes in height from its iniddletoward metal,

flange 17 which projects downwardly from the lateral flange 16 at the upper edge of the carline. As the height of the web por' tion 14 of the carline diminishes in depth toward each end, there is a corresponding increase in depth of thedownwardly profrom the middle of the carline toward each end. At thepoint wherethe vertical flange 17 thus formed reaches the plane of the bottom flange 15 on the op the web portion 1 1 of the carline whence the marginal portion of said flange 1-7 is bent outwardly forming a horizontal flange 18. Thehorizontal flange 18 increases in w1dth toward the end of the Where it terminates in a flange ot' the same width as the flangelo on the opposite side down of the marginal portion of the upper horizontal flange 15v on each side of the center of the carlineinto the vertical flange 17 and the bending horizontally of the end portion of the margin of the vertical flange 17 thus formed into the lower horizontal flange 18, which lies in the. horizontal plane of the bottom lateral flange 15 on the opposite side of the web 11, results in a earline which gradually changes from a substantially Z-shaped section at its middle into a channel section at each'cnd having lateral base flanges 15 and 18.

Each end of the carline is secured to the adjacent wooden side plate 19 by means of a channel-shaped bracket 20 which straddles the top of the side plate and is secured thereto by means of horizontal bolts 21 which. pass through both flanges ot' the channelshaped bracket and side plate 19.

The end of the carline projects over the side plate and rests on the-elnlnuel-shaped bracket 20,.which is slit crosswise on each side of its middle from the bottom of the inner flanges to the top or the outer flange. and the metal located between the slits i bent up forming a tongue jects into the ehannel-shaped end of the and is securely riveted to the under side of the flange 16 of said body member. The lateral flanges 15 and 18 located on each side of the carline are also securely riveted to the horizontal web portion of the clnumel-shaped bracket member 20. a

In the construction shown in Figs. 8 to 10 an angle bracket is shown with its horizontal flange 24 resting on the side plate of the car and projecting inwardly past the inner face ofthe side plate-and with its verdownwardly out- Then ends of the lateral flanges 15 and 18 ot the carline are bentdown as at 26 and the bracket member of the earline. The bending 23 which p ro- I and carline are secured to the side plates by means of horizontal bolts '27 which extend through the vertical flange 25 ot' the angle bracket and the side plate. The hori zontal flange ot' the angle bracketmember is 13. the bracket member 29 is channel-shaped and straddles the top of the side plate. The outer flange of the bracket is securedto the side plate by means of bolts 30 which extend horizontally throughthe side plate. Thetop web portion of the bracket member is secured in position by means of bolts 31 which extend vertically through the side plates. The inner vertical flange ofthe bracket is bent inwardly horizontally, as at 32. and forms a supportfor the end of the carline which rests thereon and has its flanges 15 and 1S riveted securelythereto. The miter flange of the bracket is slit crosswise ot' the bracket on each side of the center, and the metal between the slits isfbent upwardly in the formof a tongue which is riveted to the top of the flange 16 of the earline thereby constitutingadditional se.

vertical webs on each side of the top flange 16 ot the cal-line, thus forming a strong section adapted to resist compression stresses which have a tendency to cause buckling. This stiffening of the top flange 16 of the earline by means of the additional flange 17 also resists twisting or rotating due to the end thrust from the purlins and ridge pole.

The widening out of the ends of the carline acts after the manner of a gusset and affords wide bearing ends 'for attaching the end of the body portion of the carline to the bracket members, which in turn are securely bolted or otherwlse secured to the side plates,

while the slitting of the bracket members permits these .inembersto engage the ends of said body portion and to'be secured thereto across their entire end portion.

It is evident that the bracket members may also be used tor securing carlines ot' various commerclal shapes to the side plates till) and that changes in the above described construction may-be made without departing from the invention. 'lhcrciore, we do not wish to be limited to the exact form of carline and end brackets shown.
